DFU cycle testing

ms360

Hi ! 

I have 5 different bootloaders for 5 pieces of hardware that I would like to cycle test OTA DFU with BLE. 
I have some questions

  • Why does nrfutil dfu ble require a COM port? the DFU IOS app does not, seems strange, and also fails because I don't have a COM port connected. 
  • What's the shortest path to script a BLE DFU from either
    • Mac M2
    • RPI 5
    • Windows 10 machine

The COM port thing is holding me up in mac/windows. 
The RPI5 lack of modern python support + non x86_64 is making this seemingly simple task in to a can of worms

    Hello,

    Please note that the link you are referring to is based on an old version of the nRF Util tool (< v7.0.0), which is no longer compatible with newer versions. What version of nRF Util are you working with? (I should have asked this before.) I am using version 7.12.0, and the documentation I referenced also applies to newer versions.

    When you check the dfu ble command, you will see that it requires a second nRF device connected to the PC, which acts as the BLE adapter.

    Kind Regards,

    Abhijith

    I did figure out I need to use an nrf52 dongle. I'm on a pca10056 with connectivity firmware, plugged into the nrf USB port. Looks like we're running the same version.
